To activate the edit mode, you need to click on one of the edit links that appear on any wiki page. If you are planning to edit the whole page at once, click on the edit tab which you will find at the top of the page in your browser. This link is useful when working with new or short pages that do not have too much text. In the case of long articles, it may become difficult to find the appropriate place to edit.

Before starting with your first edit, download a copy of Wikipedia's Cheatsheet (724KB in pdf format). Print a copy and keep this close at hand when working through the tutorials. Don't worry if this doesn't make much sense now. You will use it as a reference for the next few tutorials.
